# How to uninstall Razer Synapse 2 ( https://www.razerzone.com/synapse-2 )
# on OS X (10.11-10.13) (El Capitan, Sierra, High Sierra)
# without using Razer's official uninstall tool.

# Tested on OS X 10.11.5 in July 2016.
# Edited with additional steps for later OS X versions,
# contributed by commenters on this gist.

# Step 1: In your terminal: stop and remove launch agents
launchctl remove com.razer.rzupdater
launchctl remove com.razerzone.rzdeviceengine
sudo rm /Library/LaunchAgents/com.razer.rzupdater.plist
sudo rm /Library/LaunchAgents/com.razerzone.rzdeviceengine.plist

# Step 2: Remove HID kernel extension.
sudo rm -Rf /System/Library/Extensions/RazerHid.kext
# OS X High Sierra: (Thanks to @DanThomson)
sudo rm -Rf /Library/Extensions/RazerHid.kext

# Step 3: Manually delete Razer Synapse app from Applications in Finder

# Step 4: Delete Razer files from "Application Support" folders:
sudo rm -rf /Library/Application\ Support/Razer/
rm -rf ~/Library/Application\ Support/Razer/

# Step 5: Synapse sometimes leaves a certificate installed in your Keychain.
# To remove it, open Keychain Access and click on My Certificates.
# The certificate will be called Razer USA Ltd, delete it. (Thanks to @MTCoster)
# There might an item called RAZER_KEYCHAIN_ACCESS. No certificate,
# but I suppose if you want to get rid of EVERYTHING Razer,
# you may as well go ahead and delete that too. (Thanks to @blueExcess)

# Step 6: Remove additional Razer-related files in /Library/FrameWorks
sudo rm -rf /Library/Frameworks/RzAudioSettings.framework/
sudo rm -rf /Library/Frameworks/RzSkinToolkit.framework/
sudo rm -rf /Library/Frameworks/RzStorageSDK.framework/

# Step 7: Restart your Mac.
# Expected results:
# - The Razer icon should be gone from the OS X menu bar now, and also not pop up sporadically either
# - The two processes "RzDeviceEngine" and "RzUpdater" should not be running when you check ActivityMonitor

thank you, very usefull !

What a cancer from an application - I have a feeling that it was ported somehow and not made for mac... You SAVED me from a trully terrible piece of software. People talk about malware and stuff like they are some kind of a mythical thing - RAZER SYNAPSE IS A MALWARE - don't ever install it on a mac.

Thank you.

This finally did the trick for me, it was really annoying at this point to always have the icon in the status bar left over even after uninstalling. Thanks a lot!

Works on Mac Sonoma 14.5. Thank you!

Practically you can just delete it in your folder: locations/yourmacname/library/applicationsupport/razersynapse. Do not delete the contents as it will say it is still open, but instead delete the folder. Don't need to use terminal to operate. Works on Ventura 13.4

MacOS Sonoma 14.5. Touchbar stopped working after deleting the app from Applications. The icon appeared and disappeared every few seconds. Running "Uninstall Razer Synapse" gave error "is damaged and cannot be opened"

The instruction above worked. Ran both commands for system extensions, just in case

The problem is gone, but when I restart my mac, the wallpaper is grey. Then it changes back to normal. Doesn't bother me much, maybe will go away with the next update

Life saver :) finally got rid of crappy razer software

best

still relevant today with Sequoia. TYTY!

Thanks a lot. Works like a charm

You saved me
